Fence post



YUNITED STATES PATENT OFFICE FENCE POST ration of Nebraska ApplicationDecember 2, 1932, Serial No. 645,385

2 Claims.) (Cl. 18S-29) This invention relates to fence posts and moreparticularly to metal fence posts adapted to be driven into the ground.

One of the purposes of this invention is to provide a post of thecharacter indicated which will be strong and durable and which willernbody in its structure a post body having provisions for preventingthe fence tie wires from slipping longitudinally thereof and an anchorsecurely locked to the body so as to be rigid therewith and form alateral extension thereof.

Another purpose of the invention is to provide a post which will bedevoid of rivets or other structurally independent fastening means forsecuring the anchor and post body together and one which will beeconomical to manufacture.

A further object of my invention is the provision of a novel method forconstructing and assembling my improved post.

Other objects and many of the inherent advantages of this invention willbe readily appreciated from the following description when considered inconnection with the accompanying drawing.

Referring to the drawing,

Fig. 1 is a side elevation of the bar or member which is corrugated toform the body of the post;

Fig. 2 is a perspective View of the cylinder or tubular member whichprovides the post anchor;

Fig. 3 is a side elevation of the completed post;

and

Fig. 4 is a fragmentary perspective view of the lower portion of thepost with the anchor applied.

Referring now to the drawing more in detail, reference character 5indicates generally the post body which is formed from a metal bar orrod which is shown for illustrative purposes as being cylindrical inform, although it may be of any other suitable cross sectional shape.This bar of the requisite length is provided with external projectionswhich are here illustrated as being in the form of outwardly projectingribs 6 extending partially around the body and arranged in two series,the individual ribs in one series being disposed in staggered relationwith respect to the ribs of the other series. It should be understood,however, that these outward projections may assume other shapes or formssuch as annular rings or ribs extending entirely around the body or oneor more series of spiral ribs.

These ribs or projections in whatever form serve on that portion of thepost projecting above the ground to prevent the fence tie wires frombecoming displaced longitudinally of the post. These projections nearthe lower end of the post serve likewise to hold the post anchor 5against displacement on the post.

The anchor designated generally by reference character 'l is formed froma length of cylindrical metal tubing indicated at 8 in Fig. 2 which isslipped over the lower end of the post and then 10 transverselyflattened by forging or otherwise into the form shown in Fig. 4. Thetube thus liattened firmly embraces and grips at its central portion thepost around which it is disposed, and after suicient pressure is appliedin the assembly the metal of the anchor will be displaced to accommodatethe ribs 6 of the post body and will interlock with these ribs so as tormly and rigidly lock the anchor and post body together. Either beforeor after assembly the lower edges of the anchor are chamfered off asindicated at 9 to facilitate the entrance of the post and anchor intothe ground.

In the manufacture of the fence post embodying my invention the bar orrod 5 is first pro- 25 vided with transversely extending ribs orprojections and is cut to the desired length. The cylindrical anchorlengths 8 are cut to the required lengths from tubing or pipingwhereupon the lower end of each post body is projected through itsrespective tube length 8 until this length is disposed the requisitedistance from the bottom end of the post. The tubular section is then bya forging, swedging, or similar operation flattened and tightlycompressed around the post body so that its central portion snuglyembraces the body and interts with the ribs projecting therefrom torigidly lock the section to the body. The entire piece of tubing issimultaneously flattened to its extremities so that it projectslaterally on both sides of the body providing wings which prevent thepost from rotatingl in the ground and firmly anchor it against tipping.The lower end of the post body may be chamfered off or otherwise pointedif desired to facilitate its entrance into the ground.

The details of construction illustrated and described may obviously bevaried within considerable limits without departing from the essence ofthe invention as dened in the following claims.

Iclaim:

1. A met-al fence pest comprising a post body provided with lateralprojections and an anchor rigidly secured thereto consisting of a metalcylinder surrounding said body and transversely flattened to provide acentral tubular part in snug gripping relation with said body andlateral dou'- ble walled wings.

2. A metal fence post comprising a. post body 5 consisting of a, rodprovided with transverse corrugations and a, tubular member surroundingsaid body and secured thereto by being attened into interlockingrelation therewith, said tubular Ymember comprising a. tubular partembracing the `rod and a double walled laterally projecting Wingportion. 1
